Gemcitabine and cisplatin versus vinorelbine and cisplatin versus ifosfamide+gemcitabine followed by vinorelbine and cisplatin versus vinorelbine and cisplatin followed by ifosfamide and gemcitabine in stage IIIB-IV non small cell lung carcinoma: a prospective randomized phase III trial of the Gruppo Oncologico Italia Meridionale.

the results of this trial indicate that the combination of vinorelbine and cisplatin and that of gemcitabine and cisplatin are equivalent in terms of median TTP and OS, although the vinorelbine-cisplatin regimen is associated with a higher ORR. Both regimens may be considered as reference treatments for future studies. Moreover, our data reject the 'worst drug rule' hypothesis of sequential treatments in NSCCL at least with the combination used in this study.
